Smarty: Several foreach loops within loops based on division of a given variable

The title probably doesn't make any sense at all, so I'll explain it like this:

I am going to be retrieving entires from my database and I want to format them so only 5 entires can go into each cell. Each row will have two cells, and like I said, 5 entires in each cell.

So, an example of the output would be:

_____________________       _____________________
|         Entry 1               |      |         Entry 6               |
|         Entry 2               |      |         Entry 7               |
|         Entry 3               |      |         Entry 8               |
|         Entry 4               |      |         Entry 9               |
|         Entry 5               |      |         Entry 10             |
_____________________      _____________________

_____________________       _____________________
|         Entry 11              |      |         Entry 16             |
|         Entry 12              |      |         Entry 17             |
|         Entry 13              |      |         Entry 18             |
|         Entry 14              |      |         Entry 19             |
|         Entry 15              |      |         Entry 20             |
_____________________      _____________________

..... etc...

And of course, I need it to show a cell with   if there is an uneven number of cells. And naturally, if the last cell has only say... 3 entires, I don't want the script to mess up... I would just need it to show those 3 if that's all there is.

I would prefer using the foreach Smarty function, rather than section (foreach uses much less code when the template is compiled)

Any help is greatly appreciated! :)
